- Chinese Development Aid and Agricultural Productivity: Evidence from Tanzania
Improvement in agricultural productivity plays a key role in the process of economic development. Investment in critical infrastructure has been documented in the literature as one of the pathways to boost agricultural productivity. In this paper, we ask whether foreign aid aimed at economic and social infrastructure can help improve agriculture productivity in Tanzania. To do so we combine household panel data with rich farm level information with geocoded Chinese development projects. We then exploit the the within village level variation in the total number of Chinese financed development projects in a panel fixed effects model to examine their effects of on agricultural productivity. Preliminary results indicates a positive effect on agricultural productivity in villages that are located within 25km of these projects. This is largely driven by economic infrastructure.
- Do Natural Resources make Countries poor at Taxation?
In this study, I exploit the exogenous variation in the timing of giant oil and gas discoveries to estimate the causal impact of natural resources on taxation. It has often been argued that countries that produce natural resources mobilize less non-resource tax revenues than other countries. The timing of giant oil discoveries is arguably exogenous and thus renders them appealing to empirically examine this argument as it allows one to examine the performance of non-resource tax revenue effort before and immediately after discovery as well as the period corresponding to the inflow of revenues from the production.
The study investigated the dynamic relationship between oil prices and Real GDP growth in Nigeria over time by making use of time varying Bayesian VAR with Stochastic volatility. I distinguished between supply and demand shocks by means of a sign restriction.
The study argues that the resource curse can only be avoided when the revenues generated from the exploitation of oil are invested in other productive sectors of the economy thereby decoupling economic growth from the extractive sector.
Gender dynamics in cashew and shea value chains from Ghana and Burkina Faso (with Ingram, V. J., Yago-Quattara, E. L., Mogre, D., Wijnands, J., & van den Berg, J.)
This study is part of a public-private partnership project ‘Oilseeds specialties: opportunities for the Dutch business community in the vegetable oil industry’ from 2013 to 2015. Demand is rapidly increasing for shea butter in cosmetics and food, derived from the oil rich nuts of the shea (Vitellaria paradoxa) tree and for cashew nuts, seeds of the (Anacardium occidentale) tree, used mainly as a food snack. A literature review, and interviews with 249 farmers and harvesters, processors, retailers, exporters, 42 traditional leaders, exporters, government, research institutions, non-governmental and civil society organisations and 17 focus group discussions were held between July and November 2014.
